Jun 30, 2022 (Nanowerk News) Today's artificial intelligence systems used for image recognition are incredibly powerful with massive potential for commercial applications. Nonetheless, current artificial neural networks—the deep learning algorithms that power image recognition—suffer one massive shortcoming: they are easily broken by images that are even slightly modified. This lack...
Astronauts on long missions can experience the equivalent of 10 years of age-related bone density loss
Jun 30, 2022 (Nanowerk News) Astronauts that have returned after spaceflights over three months may show signs of incomplete bone recovery even after one year on Earth, but adding in more resistance-based exercises during spaceflight may help limit bone loss. The small study, published in Scientific Reports ("Incomplete recovery of...
Metal nanoparticles serve as plant growth regulators
Jun 30, 2022 (Nanowerk News) Engineered nanomaterials (EMs) negatively or positively affect plant growth and development attributed to their physiochemical properties, application, and concentrations. Previous studies have shown that ferroferric oxide (Fe3O4) nanoparticles affect tobacco (Nicotiana tabacum) seed germination in size- and dosage-dependent manners. However, little attention has been paid...
New fossil galaxy discovery could answer important questions about the history of the universe
Jun 30, 2022 (Nanowerk News) An ultra-faint dwarf galaxy, believed to be a “fossil” of one of the first ever galaxies, has been discovered by galactic archeologists at the University of Surrey. The fossil, which was uncovered via a systematic visual search of legacy survey images using the Mayall 4-metre...
How to synthesize stable diamane at high pressure
Jun 30, 2022 (Nanowerk News) A research team led by Prof. WANG Xianlong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences (CAS) has discovered a new method to improve the stability of diamane synthesized by-high pressure method. By introducing boron (B) and nitrogen (N) dopants...
A mirror tracks a single nanoparticle
Jun 30, 2022 (Nanowerk News) Sensing with levitated nanoparticles has so far been limited by the precision of position measurements. Now, researchers at the University of Innsbruck led by Tracy Northup, have demonstrated a new method for optical interferometry in which light scattered by a particle is reflected by a...
Is AI good or bad for the climate? It’s complicated
Jun 29, 2022 (Nanowerk News) As the world fights climate change, will the increasingly widespread use of artificial intelligence (AI) be a help or a hindrance? In a paper published in Nature Climate Change ("Aligning artificial intelligence with climate change mitigation"), a team of experts in AI, climate change, and...
‘Fake’ data helps robots learn the ropes faster (w/video)
Jun 29, 2022 (Nanowerk News) In a step toward robots that can learn on the fly like humans do, a new approach expands training data sets for robots that work with soft objects like ropes and fabrics, or in cluttered environments. Developed by robotics researchers at the University of Michigan,...
Using colloidal nanodiscs for 3D bioprinting tissues and tissue models
Jun 29, 2022 (Nanowerk News) Extrusion-based 3D printing/bioprinting is a promising approach to generating patient-specific, tissue-engineered grafts. However, a major challenge in extrusion-based 3D printing and bioprinting is that most currently used materials lack the versatility to be used in a wide range of applications. New nanotechnology has been developed...
First full-scale planetary defense test against potential asteroid impacts on Earth
Jun 29, 2022 (Nanowerk News) NASA’s Double Asteroid Redirection Test (DART) mission is the world’s first full-scale planetary defense test against potential asteroid impacts on Earth. Researchers of the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS now show that instead of leaving behind a...
